Newton's Second Law

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = ma (Force = mass × acceleration).

When the same force is applied, an object with greater mass will have less acceleration compared to an object with less mass. This is because acceleration is inversely proportional to mass.

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

The object begins moving in the direction of the net force acting on it.

The acceleration is 4 m/s², calculated using the formula a = F/m (acceleration = force/mass).

A force of 12 N is needed, calculated using the formula F = ma (Force = mass × acceleration).

The relationship is defined by Newton's Second Law: Force equals mass times acceleration (F = ma).

Balanced forces occur when two equal forces act in opposite directions on an object, resulting in no change in motion.

Unbalanced forces occur when one force is greater than the opposing force, causing the object to accelerate in the direction of the greater force.

The object is experiencing a greater force to the right than any opposing forces, resulting in a net force of 40 N to the right.
